  • the external device 30 has a limited input and output interface, a method of a user checking a result or progress of a process is limited. Therefore, when the connection mode is switched, it is difficult to check progress and a result of a process according to switching in some cases. Accordingly, in a scene in which the external device 30 is used, in particular, a mechanism in which a connection mode of the external device 30 can be switched based on a manipulation from the information processing device 10 is preferable.
  • the external device 30 operated as the master unit AP and the information processing device 10 operated as the slave unit ST are assumed to be directly connected in one-to-one correspondence via the network n11.

  • the information processing device 10 after the network n11 is disconnected, the information processing device 10 has difficulty using the network n11 as a propagation path for acquiring information from the external device 30. Therefore, for example, even if a process of switching a connection mode has failed on the external device 30 side, it is difficult to check the failure of the process on the information processing device 10 side. In particular, when a device having a limited input and output interface is used as the external device 30, the above-described effect is more remarkable.
